- Short: Image processing/conversion program v1.0.1
- Author: Andy Dean and Graham Dean
- Uploader: adean@eleceng.ucl.ac.uk
- Type: gfx/conv
-
- This document applies to version 1.0.1, written on 16th September

-
- Brief description
- =================
-
- ImageStudio is written for the casual graphics user who wishes to
- convert or manipulate various graphics formats on a modest Amiga
- system. There are several commercial offerings available, however the
- casual user is paying a lot of money for many facilities and options
- they would probably never use.
-
- Bitmap graphics, by their nature, usually require large amounts of
- RAM. One of the main objectives of ImageStudio was to reduce this
- burden by utilising virtual memory - most users have more spare hard
- disk space than spare RAM.
-
- ImageStudio works with several buffers at any one time (dependant on
- how many levels of undo are specified), each of these buffers can hold
- either colour-mapped or 24-bit images. For a detailed description of
- colour-mapped and 24-bit images, See Image types.
